Why are RF Repeaters
Needed?

11
Microwave path
can not directly reach
the distant end.

Path is too long, earth
curvature blocks path.

Terrain between radio
ends is too high and
blocks path.

New building blocks
the path.
Confidential and Proprietary
Why are RF Repeaters
Needed?

Tall antenna towers
make project cost too
much.

Long distance path
clearance requires
tall towers.



Mid-path RF repeater
station costs less
than tall towers.

Confidential and Proprietary
Why are RF Repeaters
needed?

Multipath fading
makes long path
unreliable.

Outage time is
proportional to (path
length, D)3, two shorter
segments are up to
4 times more reliable.


Direct = D3
Mid Path Repeater
= (D/2)3 + (D/2)3

Benefits of RF Repeaters

Simplify radio relay route planning.




Improved system reliability.



Simple equipment is field proven,
extremely reliable.
Radio paths using RF repeaters are very reliable.
Improve multi-hop packet data networks.


14
Easy to engineer.
Site selection is easier than for
back-to-back radios.
Site engineering and installation requires less work than
for back-to-back radios.
Very low latency per RF repeater.
Very low jitter per RF repeater.

Benefits of RF Repeaters

Reduced site costs.




Inexpensive to operate.



15
Outdoor mounted equipment eliminates shelter
requirements in most areas.
Low maintenance eliminates need for frequent
road access.
Low power operation reduces mains
power equipment needed.
Solar and wind power use “free energy”.
Few components, simple.
Easy to maintain.
Confidential and Proprietary
When should RF Repeaters
be used?


When the Microwave Path is obstructed or too long.
When the Radio Relay Station does not require
circuit drops.


When the Radio Relay Station requires simple and
reliable construction.





16
RF Repeaters are “Through Repeaters”.
Difficult mountain terrain
No roads
No electric power lines
Rapid installation, quick in-service time
When a remote, unattended station requires highly
reliable equipment and low maintenance.

Relocation and Migration from 2 GHz,
Considerations for RF Repeaters

Existing path may use an RF repeater.



Higher frequency band models may be used.
Higher frequency bands may have worse
propagation.
Narrower beamwidths are more prone to
decoupling, beam wander.

Shorter hops work better.


17
30 ~ 50 km, 20 ~ 30 mi in 4 to 8 GHz.
Longer hops can become two shorter hops through
an RF repeater.
Confidential and Proprietary
Relocation and Migration from 2 GHz,
Considerations for RF Repeaters



Higher frequency bands require solid reflector
antennas rather than grids.
Narrower Beamwidths require stiffer towers.
RF repeater site may use larger antennas for
isolation requirements and also reduce the
need for larger antennas at the radio terminal
sites.


18
Reduce radio terminal site tower upgrade or
replacement costs.
RF repeater high sites typically use shorter towers.

Applications



Linear RF Repeaters are compatible with
advanced microwave radio equipment
supporting packet data traffic. RF Repeater’s
“transparency” continues to maintain
compatibility as technology advances.
Packet data is sensitive to network latency or
propagation delay.
RF Repeaters offer very low latency.
